"I think Justin has been outstanding throughout the whole thing. I don't think it's something he's distracted by," Gibson said. "He's motivated to be better. He's actually played great for us; he really has. I see him working on things. He's had a great attitude and he's been upbeat."

After going hitless in 10 at-bats to start the second half of the season in Chicago, Upton collected seven hits in the D-backs' four-game series with the Reds.

"He's played with energy and is running hard," Gibson said. "I have no complaints at all."
